A ‘Mother’ of a milestone

CBS sitcom celebrates 100th episode

The celebration for the 100th episode of “How I Met Your Mother” shifted from the Paley Center for Media in BevHills to nightspot Capitol City in Hollywood on Thursday.

Although only a few revelers were suited up, the casual atmosphere was thick with appreciation for the sitcom’s landmark accomplishment. In addition to Twentieth chairs Dana Walden and Gary Newman in attendance, the cast Neil Patrick Harris, Cobie Smulders, Josh Radnor, Jason Segel, Alyson Hannigan — and exec producers Carter Bays and Craig Thomas were also on hand to accept congrats.
